Glen White (SLAC)

22/10/2020, 07:00

Ideas are being formulated, worldwide, for electron colliders which require much shorter bunch lengths than previously considered in the accelerator community (<5um rms). These configurations are incompatible with existing BDS designs. I show short-bunch parameters being proposed and discuss challenges posed to the BDS design.
